Tattoos

I have been getting requests as of late, to do tattoos. At first, I couldn't see why someone would ask this, mainly because I myself don't have any. This is not for any other reason, than I can't think of anything I would want on me for ever. Ironically enough, I have always enjoyed looking at other people's tats. Some of the artwork is truly amazing. But just recently, a friend of mine, who has numerous tattoos, pointed out the reason for the inquiries. The ballpoint pen drawings I do, like this one, look like tattoos. He said it was the same type of work; single-line illustration. Just like artwork done on the skin, the shading is actually small lines, stacked together in a way that gives the illusion of a constant graduation of color. I had never thought of it that way. Now that I look at it, I think he might have a point.( no pun intended)
